title: Multiple sub-epidermal calcified nodule mimicking eruptive xanthoma: a case report and review of the literature.
abstract: Sub-epidermal calcified nodule (SCN) is an uncommon form of idiopathic calcinosis. It usually occurs in children, particularly in the head and neck region, presenting as a solitary, painless, yellow-white nodule with papillomatous features. These lesions occur twice as common in males compared with females. The pathogenesis is uncertain, but the clinical and histological features of this lesion are distinctive. We report a case of 22-year-old man with multiple nodules bilaterally located on the dorsum of hands simulating eruptive xanthoma. Histopathological examination of one of the excised lesion confirmed the diagnosis showing epidermal and sub-epidermal deposition of calcium. This paper presents a review of the literature and adds a new case of SCN.
